what are a steam trap?and how does it work in the system?

Answer 1

There are several types of steam traps, (Float,Bucket, Thermostatic, Impulse).

The most frequent use of traps is in steam heating where you want to maximize the removal of heat from steam as it condenses back into water. The condensate is returned via piping to an atmospheric drain tank where the collected condensate is periodically pumped back to the boiler.

Were it not for a steam trap the steam would pass through the heater without fully condensing. Eventually steam would enter the atmospheric drain collection tank(ADT). This would waste energy and condensate due to escaping steam venting from the ADT.

So Steam Traps do Trap steam in the heater and allow only the condensate to exit the heater.

The simpleset trap to understand is the float trap. This is a valve attached to a float ( Like in a toilet tank but backwards in operation) When the float rises due to an accumulation of condensate in its housing the valve opens allowing the condensate to drain. as the condensate leaves the float lowers eventually closing the valve and stopping the flow of condensate.

Thermostatic traps work off of the temperature change between condensate and steam. These traps require that the condesate subcools to say 180F before opening, once opened the condensate drains until hightemp steam is present to cause the bimetallic strip to close the valve. These traps do allow a small quantity of steam to escape (blow past) the valve.

How Do Steam Traps Work

Answer 3

a steam trap is somewhat of a misnomer its actually a water trap in a steam line...they are place at interval in loops or perhaps at ends of short drops with the steam line ...As the condensate build in the lines it drains to the trap that in turn uses this water as a piston (WATER DOES NOT COMPRESS LIVE STEAM DOES) this
very fast acting valve opening the trap for a few moments say .5 seconds...this will use the live steam pressure to clear the trap and then the spring return seals it back again...I f your live steam system becomes super saturated then you could very well get a water slug into a place like a turbine and that would not be good...water does not do well under pressure...in a steam line...now since there may be steam traps all over the place your Kewanee 200hp boiler needs conditioned boiler makeup treated water constantly that in itself is a control problem but ...that's what t a steam trap does it gets rid of condensed water....From the e....
